After an oil-and-filter change on your Smart Fortwo (W451, 2007–2015), the service indicator needs resetting so the countdown starts again. You can do it yourself with the dashboard button — no tool needed.
Before You Start
- Do the oil and filter change first — resetting only clears the reminder.
- The timing matters — have everything to hand before you begin.
Resetting the Service Indicator
- Turn the ignition on.
- Within the first 4 seconds, select the service indicator by pressing the button twice.
- Within 10 seconds, turn the ignition off — the service indicator stays on the display.
- Press and hold the button, then turn the ignition on again.
- The service indicator flashes, then shows the remaining distance to the next service.
- When the indicator goes out, release the button and turn the ignition off.
If the Reset Doesn’t Take
- Mind the timing — the double-press must be within the first 4 seconds.
- Repeat the sequence from the start if it doesn’t clear.
- A wrench/spanner warning that won’t clear can store a code — look it up on autodtcs.com.
